Majority of the million tons of plastic produced each year is being disposed after single-use. Plastic bottle, bags, food containers, gloves, and cup that end up in landfills and environment could linger for hundreds to thousands of years. Moreover, COVID-19 pandemic caused by the novel coronavirus (SARS-CoV-2), will also exacerbate the global plastic pollution as the use of personal protective equipment (PPE i.e., gloves, masks) became mandatory to prevent the spread of the virus. Plastic eventually breaking down in micro & nanoscopic bits due to physical or chemical or biological actions in the environment, can enter animal and human food web. So, plastic management programs need to be more robust with a focus on the prevention of the micro and nanoplastics entrance into the environment and food web. In the present pandemic situation, it is even more necessary to know about how much plastic waste is being generated and how different countries are coping up with their plastic waste management. In this review, we have elucidated how global plastic production rise during COVID-19 and how it would contribute to short and long-term impacts on the environment. Plastic pollution during the pandemic will increase the GHS emissions in the incineration facilities. Improper disposal of plastics into the oceans and lands would endanger the marine species and subsequently human lives. We have also assessed how the increased plastic pollution will aggravate the micro and nanoscale plastic problem, which have now become an emerging concern. This review will be helpful for people to understand the plastic usage and its subsequent consequences in the environment in a pandemic like COVID-19.

The stroke patients comprise a large number of hospital admissions and stroke is one of leading cause of significant mortality and morbidity. This prospective observational study was carried out among 100 hospitalized stroke patients admitted into different medicine units of Chittagong Medical College Hospital (CMCH), with a view to study clinical presentation and epidemiology of stroke. Data, collected in prescribed protocol, were analyzed in simple statistical percentage and cases were selected irrespective of age and sex. Stroke was found most commonly in 51-60 age group (45%in hemorrhagic and 51.75% in ischemic stroke).Most of the patients were male with male, female ratio 3:1 in hemorrhagic stroke and 1.35:1 in ischemic stroke. Most of the patients were from rural area (60% in hemorrhagic stroke and 57.5 in ischemic stroke). Ischemic stroke was found in 80% cases and hemorrhagic stroke was found in 20% cases. The commonest presentation in both ischemic and hemorrhagic stroke was hemiplegia or hemiparesis. Rightsided hemiparesis was the predominant finding in both types. Headache (60%) and vomiting (75%) were found to be more common accompaniment of hemorrhagic stroke. In case of ischemic stroke the association with these clinical features was less marked where headache was present in 46.25% and vomiting in 40% cases. 50% of patients of hemorrhagic stroke presented with Glasgow Coma Scale (GCS) level 9-12(grade2) and 5% with GCS level 4 - 8(Grade 3). Whereas, 52.5% of patients of ischemic stroke presents with GCS 9-12 and also 46.25% with GCS13-14 (grade 1). Hypertension was the commonest risk factor associated with both types of stroke. In hemorrhagic stroke it was 80% and in ischemic stroke it was found in 56.25% eases. Smoking was associated with 50% of hemorrhagic and 55% of ischemic stroke. Diabetes mellitus was associated with 26.25% of ischemic stroke   doi: 10.3329/jom.v10i2.2820 J MEDICINE 2009; 10 : 86-89

Melanosis Coli is described as black or brown discoloration of the mucosa of the colon. It is a benign condition, whicharises from anthraquinone laxative abuse and usually has no symptoms of its own. Though not a very rare condition,to the best of our knowledge, no case has been reported on melanosis coli in Bangladesh . Here we report a case ofmiddle aged lady presenting with passage of blood mixed stool for one year. Colonoscopy was performed whichrevealed melanosis coli and which was later confirmed by histopathology. Not thought to be a pre malignantcondition, it has been found in some patients with other diseases.Keywords: Melanosis coli; Anthraquinone; Lipofuscin; Laxative; BangladeshDOI: 10.3329/jom.v11i2.5469J MEDICINE 2010; 11 : 183-185
